I'm a Grateful Dead fan (so's my dad. his truck has a giant Geadhead graphic on the back)and I wanted to do this the second I thought of it, so I did it.
The innovation here is the headband of flowers that's made from a blue lego rubber band, 7 red lever bases, and a yellow lever. I'm pretty sure it's not been done before.
Just loop the whole rubber band threw each of the bases then put the yellow lever to keep the two ends together. When it goes ontop of the head and wraps around the stud it expands a little to make it look more like roses.
Very creative shot/minifig ! I'm a Grateful Dead fan too, and it's rather uncommon in France ^^ This is really a great band, I'm especially fond of the song "Ripple" and the LP "Wake of the flood"... But obviously nothing can't beat "Darkstar" :-)
